Cautions and Warnings 1. Read and follow all operating and installation instructions. 2. Always follow gate operator manufacturer installation instructions regarding installation of Type B1 sensor and operator. 3. Disable the gate so it is unable to move. Refer servicing to qualified service personnel. IMPORTANT: This product is an accessory or part of a system. Always read and follow the manufacturer s instructions for the equipment before connecting this product. Comply with all applicable codes and safety regulations. Failure to do so may result in damage, injury or death. Retroreflective photoeyes rely on a reflective surface (a reflector) for proper operation. In some cases a vehicle with reflective surface at a given distance can act as a reflector and allow the gate to close on a vehicle. EMX Industries Inc. assumes no responsibility in this case and all the risks are on the installer, designer and user of the gate system with a retroreflective photoeye. In case such a risk is not acceptable, EMX Industries Inc. strongly recommends the use of a thru-beam type of a photoeye. Product Overview The NIR-50-325 retroreflective photoeye is an external entrapment protection device Type B1, non-contact sensor for use with automatic gates and doors. The light beam is pulsed near infrared. Since the reflector directs the beam back to the photoeye, wiring to the other side of the roadway is not required. The NIR-50-325 provides a signal to the gate or door operator that the beam is not obstructed. The operating range is up to 50ft. The NIR-50-325 operates over a voltage range of 12-30VDC and 24-30VAC. Two LED indicators provide status information at a glance, making set-up and alignment easy. A yellow LED indicates signal stability. A red LED indicates alignment with reflector (off when obstructed). The NIR-50-325 is configured for normally closed (NC) and 10k monitoring by the operator and complies with UL325 requirements effective August 1, 2018. The 10k termination resistor is built into the photoeye. Refer to operator manufacturer s instructions to ensure compatibility. Refer to operator installation instructions for proper monitoring selection. NIR-50-325 Operating Instructions 2

The intent of External Entrapment Protection Device Type B1 non-contact sensor is to protect a person from being accidentally injured by the moving gate or door. 1. Always follow the instructions of the gate operator manufacturer regarding installation of Type B1 sensors on the gate operator. The instructions of the gate operator manufacturer always supersede any instructions given in this or any other instructions by EMX Industries 2. When using the relay outputs, do not exceed the voltage/current ratings indicated in the specification table. The recommended alignment technique is to mount the NIR-50-325 at the desired location and hold reflector about 3 feet in front of the unit while watching the lights to assure that both remain lit. Move backward to the desired mounting location for the reflector. You may have to move the reflector up, down, left or right to keep the reflector in the middle of the signal path. This ensures NIR-50-325 Operating Instructions 6
the least troublesome setup by keeping the reflector off the edges of the signal where any movement may take it out of alignment. NOTE: The signal pattern is only 2 feet in diameter Verification and Operation Verify proper operation of the NIR-50-325 according to instructions from the gate operator manufacturer. The intent of External Entrapment Protection Device Type B1 non-contact sensor is to protect a person from being accidentally injured by the moving gate or door. 1. Verify that the NIR-50-325 and reflector are in line of sight and apply power. Confirm that the red LED and yellow LED are on, indicating power and proper alignment. 2. Place an obstruction (ex. hand) between the NIR-50-325 and the reflector. Ensure the yellow LED and red LED turn off. Check the operator control board and verify that the safety input is actuated. 3. Remove the obstruction and the yellow LED and red LED will turn on. 4. Follow gate/door manufacturer s installation instructions and safety checks to verify that the NIR-50-325 is operating properly. Troubleshooting Symptom Possible cause Solution Unit stays in detect No output No detection Unit out of alignment Reflector covered with dirt, dust, snow, or water Water inside reflector No Power Bad connection, wires broken Improper wiring Unit not powered Other reflective surface causing signal return Verify alignment Clean reflector surface of contaminants Replace reflector Check power and wiring as per chart on page 4 and 5 Check connections Verify wired to correct inputs on operator Check power Check surrounding area for reflective surface NIR-50-325 Operating Instructions 7
